Description
The Rubber Stoppers, One Hole for Tubing, also known as one-hole laboratory rubber bungs, are designed for use with compatible laboratory glassware, bottles, flasks, test tubes and tubing assemblies. Each stopper includes one hole, allowing compatible glass tubing, plastic tubing or laboratory fittings to be inserted where the selected setup requires a pass-through connection. The range includes sizes from No. 1 to No. 14, with dimensions listed as T × L × B in millimetres for size selection. These stoppers are useful for general laboratory sealing, gas delivery demonstrations, simple reaction setups, filtration arrangements, school science experiments and teaching laboratory apparatus assemblies.
Users should confirm the vessel mouth diameter, stopper size, hole diameter, tubing diameter, chemical compatibility and operating conditions before ordering or use. Do not force tubing through the stopper hole. Use appropriate insertion technique and protective gloves where glass tubing is involved to reduce breakage and injury risk. Rubber stoppers should not be used with incompatible chemicals, excessive heat, open flame, strong solvents or unsupported pressure and vacuum conditions unless the full setup has been confirmed as suitable.
This product is intended for laboratory or educational settings only and should be used under appropriate teacher or laboratory supervision. This item is supplied as the selected one-hole rubber stopper only. Glass tubing, plastic tubing, bottles, flasks, clamps, stands, connectors and additional laboratory accessories are not included unless specified separately.
LabChoice Australia supplies Rubber Stoppers and laboratory sealing accessories for school science laboratories, university teaching laboratories and general laboratory environments requiring practical components for compatible glassware and tubing setups.
